Title: Fluorescent poly(arylpyridine)rare eath chelates
Inventor: HALE RON L
IPC: C07D213/81
Filed: 1988-11-04
Granted: 1998-03-17
Abstract: A class of fluorescent rare earth chelates and the ligands upon which they are based whose molecular structure incorporates a plurality of substituted arylpyridine diacid units attached to a central template structure is disclosed.  These ligands function as efficient energy transfer groups in fluorescent tagging reagents and tracers.  The present fluorescent chelates contain a plurality of aryl-substituted pyridines arranged structurally within a single molecule such that each optimally binds to a single metal ion.  Each pyridine group is structurally insulated from the others so that, in the unchelated form, each retains to some degree the properties of the single pyridine.

Abstract: EXERCISE APPARATUS ADJUSTABLE DURING USE ABSTRACT OF THE DISCLOSURE      The apparatus comprises a carriage supported on a track assembly by rollers.  Energy absorption and release apparatus biases the carriage toward an at-rest position approximately midway between the ends of the track assembly.  The user lies back-down on the carriage and, using handles and a foot rest provided for the purpose, sets the carriage into reciprocating motion.  The effort used in causing the motion and the acceleration  forces  experienced  as  a  result  of  it provide effects beneficial  to  the  user's  voluntary  muscles,  skeletal  muscles  and internal organs.  The energy absorption and release apparatus comprises primary  and  secondary  apparatuses.   The  forces  and  energy  levels involved in the operation of both the primary and secondary apparatuses is adjustable while the apparatus is in use, the secondary apparatus being adjustable by the user.  The adjustments are effected by manual engagement and disengagement of units of sets of bungee apparatus incor-porated  in  the  primary  and  secondary  energy  storage  and  release apparatuses.

Abstract: Disclosed is an electro-pneumatic or electro-hydraulic converter or actuator with a pneumatic or hydraulic nozzle-flap system or similar, which is controlled by an electric control signal. The electric control signal is a pulse sequence signal oscillating at a constant or variable frequency, the duty-cycle of which is varied proportionally to an input signal. The flap or similar is essentially arranged to oscillate in the linear range of its characteristic curve, so that it never completely opens or closes the nozzle or similar, which feature is provided by mechanical stoppers and/or by selecting said frequency sufficiently high. The invention thus provides a converter or actuator, with improved response speed and linearity and which shows minimal hysteresis.

Abstract: A field portable X-ray fluorescent spectrometer is described including a multichannel analyzer (2) and a plurality of interchangeable sensor heads (4). Each sensor head includes a shutter (100) which, when open, permits one of several radiation sources (80, 82) to irradiate a material to be analyzed. The returned radiation is detected by a corresponding detector (86, 90), which provides corresponding data in response. This shutter has calibration plaques attached to it so that, when closed, the plaques are exposed to the radiation sources and return radiation having selected energy distributions to the detectors. The multichannel analyzer uses the resulting detector data to calibrate the sensor head. Each sensor head includes circuitry (290) for identifying itself to the mutichannel analyzer. The analyzer automatically adapts its operation in accordance with this identification. When the shutter is open, the multichannel analyzer utilizes the detector data to accumulate an energy spectrum of the material being analyzed, and displays the spectrum on a display screen (12). A cursor control (28) allows the operator to move a cursor along the displayed spectrum. A display (32) is automatically provided with a display of the symbol of the element, if any, having its major spectral peak at the position identified by the cursor. Secondary indications identify other positions along the spectrum at which peaks would appear if the element were present. Memory (202) is provided for storing a number of reference spectra, any of one of which may be displayed on the screen along with the acquired spectrum for comparison purposes. The memory (202) also stores previously acquired spectra for later analysis. The analyzer also includes other operational features, such as normalization, window control, and ratio and concentration determination, to permit the operator to quantitatively analyze material in the field.
